One of Dr. Bishops earliest granted patents was in 1958 for his perfected variable ratio rack-and-pinion power steering technology. Since then, Bishop has filed over 500 patent applications, with over 100 of them successfully registered. The company’s rack-and-pinion steering gear, one of its most successful inventions, is the subject of an international Patent Cooperation Treaty (PCT) application. The Bishop ATS Power Steering Valve and the Bishop VARIATRONIC, a speed-sensitive power steering solution, are further examples of the SME’s patent registrations and innovative success. Bishop has prodigiously used the PCT System to file patent applications internationally and to obtain patent protection for more than sixty technologies and processes in many different international markets.
